This game is similar to the Soviet classic Tetris, except that rows of blocks move up from the bottom of the screen rather than falling one at a time from the top. Your goal is to clear blocks by making complete rows without any gaps. You can slide blocks left and right by clicking and dragging them, and they will fall due to gravity when you let go. You get more points for clearing more lines in one move, so setting up chains is a good strategy. When the blocks reach the top of the board you lose.
